Gas/oil fired commercial vacuum hot water boiler, operates under negative pressure. It is safe & reliable, never explode. The SU304 stainless steel tube heat exchanger has high heat transfer efficiency, low heat loss and low exhaust gas temperature.
Low water conditions will literally melt the steel pressure parts. Typical industrial boilers are “natural circulation” boilers and do not utilize pumps to circulate water through the pressure vessel. These units rely on the differential density between hot and cold water to provide the circulation.
As a form of direct heating, a significant heat transfer surface between the water and the process is required for the heat transfer to work efficiently. Where the process does not allow for this, or if the required water temperature is above 100°C, the use of High-Pressure Hot Water Boilers is a tried, tested and proven solution.
Unlike a car, the "gas mileage" of your average boiler will degrade over time due to scale and sludge deposits. Putting aside for a moment that many "high efficiency" boilers will also require high cost maintenance, a boiler's operating cost can be boiled down to this simple equation: Fuel burned in a new boiler = cost to operate new boiler.
Tube failure in high pressure boilers follow a normal bath tub curve, with higher rate during initial operation period, stabilizing to a lower rate during the normal operating period and again increasing as the boilers age and cross ten to fifteen years of operation.

Johnson boiler: one of the first "modern" classes of high-pressure marine oil-fired water-tube boilers. They have a single steam drum above a single water drum. Their small-diameter water-tubes curve outwards on each side to form a cylindrical furnace.
They accomplish this by boiling water at subcritical pressures with intricate fuel systems. In some jurisdictions, the high pressure and high steam output capability of steam boilers requires a fully certified and licensed operator to be on-site in order to be operated. There are two common designs for a steam boiler: firetube and watertube.
A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel , to produce vapor and hot water for heating and processing loads.
